IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent N 0. 222,894, dated December 23, 1879; application filed July 30, 1879.

To all whom it may concern Be it known that I. ANDREW GOODYEAR, of

of Michigan, have invented a new and useful,

Improvement in Plows, of which the following is a Specification.

My invention consists, first, in a sectional beam designed as an improvement upon my Patents Nos. 213,158 and 218.5l7, wherein a .)low-sta-ndard is provided with a cross-head having a curved and corrugated front surface, to which to attach a beam, and whereby to change the angle of such beam with reference to the line of motion of the plow; and it further consists in combining, with the curved stock of aplow, an arm of peculiar construction for holding in position a jointcr and for determining its position.

In the annexed drawings, making a part of this specification, Figure 1 is a perspective view of the plow. Fig. 2 is a rear elevation of the same. Fig. 3 is aside elevation of the standard, showing thelugs to which thejointer is attached. Fig. 4 is a perspective view of the jointer. Fig. 5 is a plan view, partly in section, showing the handles and manner of attaching, at the lower end, to the standard. Fig. 6 is a perspective view of the clutch which holds the lower ends of the handles together. Fig. 7 is a perspective view of the forward end of the curved beam. Fig. Sis a perspective View of the end of the beam proper. Fig. 9 is a vertical section, showing the two sections of Fig. 10 is a per spective view of the brace used for securing one of the handles in place.

The same letters are employed in all the figures in the indication of identical parts.

A is the standard of the plow, curved forward, as shown, to form a portion of the beam, and is also constructed with an arm, B, extending to the rear and braced by the brace B, to which one of the handles is attached. The upper front end, 0, of the curved standard A is rounded to form a cross-head, G, which cross-head has two slots, 0 G and it is also provided with vertical corrugations 0 C The lower side of the beam (lis provided with a lug, D, which is perforated at D to re cross-head, F, curved in the opposite direction, so as to fit on the crosshead C. It is also similarly slotted at F F, and corrugated at F F, so that when the two are brought together end to end the slots will coincide, and the corrugations fit into each other and be held in'position by the bolts 0 (3 which are threaded and provided with nuts.

The forward end of the beam F is provided with a clevis, G, and it is also corrugated and curved, as shown at H, Fig. 1, to admit of the adjustment of the shackle-wheel H. The curved portion of the beam is slotted longitudinally to receive a bolt, which passes through the standard H of the wheel, which is also slotted; but instead of the slot being longitudinal it is vertical, so that the wheel can be adjusted at any height. The rear face of the standard H is also correspondingly corrugated as the beam F. Just in rear of the corrugations in the beam there is, on its under side, a lug, I, provided with a hole to receive the front end of the draft-rod. E, which is held by two nuts, one on each side of the lug I. This draft-rod, in addition to giving strength to the beam, also affords a means for raising or depressing the end of the beam when wishing to plow more or less deep, the rounded surfaces of the two cross-heads allowing this to be done. By means of the curved crossheads provided with longitudinal slot-s the line of draft may be changed, the beam F being securely held in position when changed by the corrugations U and F F, engaging one another and the bolts Q C. When such change is made the direction of the wheel H must also be changed, otherwise it would be drawn sidewise, and this is accomplished by moving its standard along the curved surface H, the horizontal slot allowing the bolt in the standard to be so moved. It is also necessary to change the tension of the draft-bar E by means of the two nuts on its forward end.

On the land-side side of the standard A are two lugs, K K, to which are attached the jointer L by means of bolts passing through the j0inter-arms, thelngs, and standard. The lugs K and K are corrugated at K and re cessed at K respectively, to receive correceive one end of the bent draft-rod E. The sponding corrugations L and a lug, L, on detachable beam F is provided with a similar the arms L and L of the joiuter. The arm L is slotted at L to admit of its adjustment, so that when required to raise or depress the point of the jointer it can be done by simply loosening the bolts L L ,-the lug L turning in the recess K in the lug K. The object of the lug L is that in case any sudden oreX- traordinary strain is put on the jointer, it greatly relieves the bolt, which in ordinary jointers are continually breaking. Having two arms instead of one also serves to add greater strength, one acting as a brace to the other.

M is a small wheel, placed inside the landside, and has a double face, hearing both against the bottom and. side of the furrow, thus greatly reducing the friction. This wheel is not attached directly to the land-side, but to an arm, M, which is placed at an inclination with the land-side, and slotted, as shown at Fig. 1, so as to allow the wheel to be vertically and laterally adjusted, the wrist-pin M moving in said slot. The upper end of the arm M is bent into a vertical position, and provided with a hole to receive one end of the brace-rod N, which extends from said arm M to the inner face of the mold-board, and is provided with double nuts, one on each side of the arm, thus holding it secure.

The arm M performs the double function of aifording an arm to which to attach the wheel M, and also forming a part of the brace for the mold-hoard.

O and Oare'the handles, which may be adjusted at any required height by having the lower ends confined by the clutch which is formed with a flange, O entering, when placed in position, a recess on the inner side of the standard, to which it is attached by a bolt passing through the standard, clutch, and handles, on which bolt the handles turn, and thus they may be placed at any required inclination, and held in such position by bolts which pass through the handles and slots formed in the rear extension of the plow-standard and in an arm, P, which is securely bolted to the inner side of the moldboard, just above the brace-rod N, the shape of this arm being clearly shown in Fig. 10.

In order to hold the handles more securely in position there is provided a brace-rod, Q, which extends from the bolt which secures the handle 0 to the arm P to the standard A, where a slot, R, is formed to receive the bolt which attaches it to the standard. By means of this slot the rod Q may be moved to ac commodate itself to the inclination of the handles.

I am aware that jointers haveheretofore been used, and that they were attached to the plow-standard; but mine differs from these in this, that instead of using but one arm I use two, which give great additional strength; also in the use of the lug on one of the arms, which relieves the bolts in case of sudden strain. Wheels placed on the inner side of the landside, near the rear, have also been frequently used, but the manner of attaching them differs greatly. The arm which allows my wheel to be adjusted both vertically and laterally also forms part of a brace for the land-side and mold-board.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the stock A, having the curved and vertically-corrugated front face, with the beam F and rod E, all arranged to operate substantially as set forth, and for th purpose specified.

2. In combination with the curved stock A, the bifurcated arm L and L having its upper prong corrugated and slotted, and its forward end grooved for the reception ofa jointer, L, the arrangement of parts being as shown, whereby the arm is carried upon the stock of the plow, and the jointer is made adjustable vertically, as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses. I

ANDREW GOODYEAR.
